“…They concluded that the combustion of liquid fuels using porous inert media could be a viable approach for gas turbines and other similar applications. Takami et al (1998) attempted to develop liquid fuel porous ceramic burner without using a fuel atomizer, as extension to the work of Tseng and Howell. They supplied kerosene (instead of heptane) dropwise (instead of in droplet spray) to the top surface of a horizontal porous ceramic plate burner through a steel wire net which served as a distributor for the fuel.…”

“…In [6][7], the effect of a porous media arrangement was studied on a CH 4 /air combuster, and the experimental and simulation results indicated that the inner and outer layers had a positive impact on the combustion process. Many studies focused on the usage of liquid fuels, such as kerosene and ethanol [8][9][10][11][12]. In [13][14], a comprehensive review of research and development in the combustion of liquid fuels within a porous medium was carried out.…”

This study investigates the effect of packed bed material porosity and air-to-fuel ratio on the combustion stabilization of a premixed gaseous mixture. An experimental work was carried out in a single-layer concept of a packed bed on a constant cross-sectional area tubular burner. Two types of materials, Alumina (Al2O3) and Zirconia (ZrO2), with different porosities, namely 0.36, 0.4, 0.44, and 0.46, were tested. The results showed that porosity has a significant effect on the position of the reaction zones. As porosity decreases, the reaction zone moves downstream of the packed bed. The excess air ratio does not affect the position of the reaction zone but has an impact on the temperature distribution inside the porous medium. The packed bed material affects the volume of the reaction zone and the temperature distribution inside the porous media, where Zirconia has a reaction zone volume higher than Alumina. The concentration of NOx was reduced with increasing porosity. Zirconia media exhibits a lower level of NOx emission compared to Alumina. For an excess air ratio of 1.6, the maximum NOx values were 22.5 and 17.5 ppm for Alumina and Zirconia, respectively.

“…Similarly to premixed combustion, after mixing with the oxidants, the fuel then enters the main combustion zone for combustion. Takami et al [23] developed a liquid fuel porous burner without an atomizer, which supplied kerosene dropwise into the metal mesh, and used porous ceramics as fuel distributors and evaporators. The experimental results showed that the lean-burn limit equivalent ratio of kerosene could be extended to 0.1, and the turndown ratio could reach 7.2.…”

Experimental Investigation of a Self-Sustained Liquid Fuel Burner Using Inert Porous Media

et al. 2023

A self-sustained porous burner without a sprayed atomizer was built for diesel oil. It consisted of metal fiber felt as an evaporator upstream and ceramic foam as an emitter downstream. The liquid fuel underwent film boiling in the porous evaporator and was rapidly evaporated by the heat recirculated from the porous emitter to the porous evaporator through intense irradiative heat flux. The effect of the porous structure and its installation location on the performance of the porous burner was investigated. The results indicated that the evaporation and combustion of liquid fuel could be prompted by the radiation of porous media. The position of the flame moved downstream, and the flame temperature decreased when the distance between the metal fiber felt and the ceramic foam was increased. The lowest NOx concentration was obtained when the distance between the foam and the metal fiber felt was 90 mm. When the diameter of the central hole of the ceramic foam was increased, the position of the flame moved towards the burner outlet, and the flame temperature and NOx emission declined. The flame temperature of the divergent configuration as emitter was higher than that of the convergent configuration, and the flame temperature of the C–D configuration was higher than that of the D–C configuration. Different ceramic foam structures had a significant effect on the temperature and emission in the combustion chamber, which showed that the evaporation and radiation performance of inert porous media burners with different structures is quite different.
